Blockchain-based notarization platform

Tech Lead

Managing the dedicated team on the project

Marco Drost

Develop a solution that will allow owners of documents to confirm, transfer and share their ownership and have information of the latest signed document on the blockchain.The development of backend and frontend, development and audit of Ethereum smart contracts, blockchain consulting and business analysis.

Lead backend and blockchain developer on the project. I was responsible for core system development - the blockchain database, that's stored and synced between all users.For the blockchain tech was chosen Ethereum, as a widely used technology that also allow the
smart contracts functionality from the box. There’s an additional layer on node.js for registrations and storing additional info. Backend provides API for the mobile app.

Own startup

RecycleChain is an open market for
recyclables. Core of the system is the
blockchain database, that’s stored and
synced between all users. It will hold
next data:
1. Amount, type and price of waste in
possession of each player
2. Ownership transactions in a form of
smart contracts
3. Trading balance in the internal
blockchain currency (cryptocurrency)

I was responsible for token and a smart contract development that connects emission to the mining process of the farm. So whenever a bitcoin is mined – a token value changes. In this way bitcoin plays the previous role of gold in the paper money emission. Connection was built on BTC Relay tech.

Taras Kornichuk

We integrated Bitcoin and Ethereum blockchains via middleware. The purpose of it to act as a centralized smart exchange with the liquidity of Tokens and BTC that are held inside. Price discovery of exchange will be done by formula, so no more bids/asks.

I was responsible for designing the tech solution for Terra-Bridge protocol, development and publishing it into production. Now, this project is open -sourced and I am the main contributor.

Peter He

Protocol for Interchain Token Transfers between Ethereum and Bitcoin.The purpose of this proposal is to establish in details the mechanism for permission-less transferring of assets between Ethereum and Bitcoin. Usecases: Cross-chain transfer between Ethereum and Bitcoin is useful in fields such as: Stable coins, Decentralized exchange, Financial derivatives: More info on https://www.contractland.io/

This project was developed at London Blockchain Week Hackathon. I was tech lead and lead blockchain developer on this project ( used ERC 721 Token)

Own blockhain project

Crypto Kitties had huge success in the Ethereum network. It game mechanics is pretty simple, but with the concept of ownership and commerce, it was enough to drive people. We'd like to test same mechanics in the traditional gamification space – as a motivational tool for good moves and work.

Provided the security audit of 9 smart contracts for their upcoming ICO. BitRent (RNT) is the blockchain platform meant to attract commercial and residential property investments at an early stage.The resulting report in the excel included 37 found issues.After the rework, new version of contracts was checked and contained no found vulnerabilities. Presale was launched.

Vitalik Ermakov

We’ve audited a set of smart contracts for the crowdsale. Logics
included presale, gnosis multisig wallet, lockdowns and pauses.
There was a set of 38 issues found. 3-4 high
impact vulnerabilities, 5-6 medium, else low and notes.
